ENFOQUE TRANSFRONTERIZO PARA LA SOSTENIBILIDAD DEL AGUA
Europa debe hacer más para garantizar el uso sostenible del agua si no quiere perder la batalla contra el cambio climático. Y que corre riesgos cada vez mayores de sufrir sequías e inundaciones.
Para ello se han establecido
objetivos de cara al 2020, similares a los del consumo energético: aumentar un
20% el ahorro de agua en todos los sectores, aumento del 20% de los cursos
fluviales en los que se lleve a cabo una regeneración para reducir el riesgo de
inundaciones y aumento del 20% de agua reciclada en las agricultura.
Se
le pide a los miembros de la Unión Europea que adopten medidas para poder
llevar a cabo la eficiencia a nivel de las cuencas hidrográficas por cada
sector de actividad que depende del agua: domestico, industrial, agrario,
piscícola, turismo, energía hidroeléctrica…
La UE propone integrar los
objetivos sobre la eficiencia energética e hídrica de los edificios y adaptar
los objetivos de eficiencia a las necesidades de cada zona.
Esta propuesta de la Unión Europea
me parece muy importante ya que estamos acostumbrados a malgastar agua, tanto
en el casa como en los demás sectores: agricultura , industria…
Solo cambiando un poco los hábitos
domésticos se puede ahorrar mucha agua, cerrar los gritos, poner la lavadora
cuando este con toda la carga, lo mismo con el lavavajillas, cerrar la ducha
mientras nos enjabonamos y así un montón de pequeños gestos.
En la agricultura y jardines poner
riego por goteo, aprovechar el agua de la lluvia, utilizar agua reciclada…
Son pequeños detalles que no nos
cuesta nada y con un poco de todos hace mucho.
Quizás los gobiernos serian los que
tendrían que colaborar más con leyes o
educación ambiental en los colegios o medios de comunicación.
INDULTOS EN PLAYAS DE HUELVA
La ría de punta umbría y los caños de cepo y el casco urbano de isla cristina queda fuera de la nueva ley de costas. Estos espacios se han excluido del dominio público marítimo terrestre por ser núcleos urbanos consolidados antes de 1988. Pasando los titulares de las viviendas en esta zona a tener la propiedad.
Según los ecologistas esta ley de costas perjudica al
litoral.
La norma es una amnistía y supone una privatización de
espacios marítimos terrestres. La
reducción de la franja de protección del litoral de 100 metros a 20 en costas
tan dinámicas colmo las andaluzas, según ecologistas en acción.
Se ha comprobado en Isla Canela que genera, perdida de
playas, subida del nivel del mar…
Sin embargo los políticos defienden la seguridad que les dará
a los propietarios de las 970 viviendas y los 70 chiringuitos.
Visto desde este punto de vista podríamos pensar que no esta
mal. Ya que dejar a casi mil familias sin casa sería un grave problema. Lo
mismo pasaría con los propietarios de los chiringuitos y los empleados que trabaja
allí.
Lo que me parece inadmisible es que se halla pasado de
100 metros a 20. YA que lo aprovecharan para construir. Dejando sin playa zonas,
sobre todo en las zonas turísticas donde
se seguirán haciendo espigones y cambiando todo el litoral.
Esto a la larga no es beneficioso para nadie. No tenderemos
espacio para tomar el sol, ya que estarán dando permisos a 20 metros del mar,
perjudicando de este modo no solo a las personas sino a todo tipo de aves
marinas...
Una prueba de ello la tenemos en nuestra provincia el Algarrobico,
construido en pleno parque natural.
EL DIÓXIDO DE CARBONO EN LA ATMÓSFERA LLEGA A NIVELES
MÁXIMOS EN LA EVOLUCIÓN HUMANA
El nivel de dióxido de carbono, que es el gas que más
contribuye al calentamiento global, ha alcanzando las barreras máximas. Tenemos
unos niveles nunca antes vistos en millones de años, según los científicos.
La media diaria supera las 400 partes por millón. Aunque se
trata de un momento aislado, esto nos recuerda que el esfuerzo para controlar
la emisiones provocadas por la actividad humana han fallado.
Los científicos creen que la cantidad de tras no había sido
tan alta desde hace 3000 millones de años, antes de que los humanos hubieran
evolucionado.
Ralph Peeling que dirige uno de los programas sombre
emisiones de CO2 en San Diego ha declarado que un aumento continuado podría ser
catastrófico. Estamos perdiendo la
posibilidad de mantener el clima por debajo del umbral que sería tolerable.
Los dispositivos de Hawái, que desde hace medio siglo llevan
tomando muestras de aire limpio o fresco del aire que circula por el océano
Pacífico, es la primera vez que detectan estos niveles tan altos.
Los niveles de dióxido de carbono aumentan y descienden en
ciclos temporales pero nunca habían llegado hasta estas proporciones.
Cada día oímos noticias referentes al cambio climático y los
expertos nos recuerdan que nos estamos cargando el planeta.
Aunque en este caso los niveles de dióxido volverán a bajar,
poco a poco en unos años llegará el
día que no bajen, que haya menos oxigeno, que terminemos con el medio y que no
podamos ni salir a la calle debido a la contaminación.
CAT ADOPTS DOG

Things didn’t look good when Charlie the rottweiler was born at Meriden Humane Society. Charlie’s mother was too sick to nurse him, and workers struggled to keep the puppy healthy by bottle-feeding him every two hours. Luckily, Satin the cat came to the rescue.
Satin was nursing her own kittens, and exhausted workers hoped she might be willing to add one more to her family. “She loved it when we put them together,” says director Marlena DiBianco. Satin fed Charlie for three and a half weeks. Her kittens welcomed the puppy like a brother, wrestling and sleeping with them.
In 17 years at the shelter, DiBianco has never witnessed anything like a cat nursing a puppy. That didn’t matter to Satin. Even as Charlie grew, the cat still mothered him. “He was twice her size and she would still groom him,” DiBianco says.

Charlie
is a Rottweiler, and when he was born her mother can’t nurse him because she
was to sick. So workers, nurse the puppy by bottle-feeding him every two hours.
The
workers decided to add to a family’s cat and fortunately the cat accepted the
dog and feed him for three and a half weeks. The little cat welcomed Charlie like
a brother.
The shelter
was surprised because he has never seen it before but Satin said that this was
because of the appearance of the dog, similar of the cat.
This is
a nice new about animals. It shows that animals can help other animals, and
also that is better that animals nurse other animas than people nurse it. This
case seems surprising, but there isn’t the first case, in some zoos the workers
have investigated about that, putting together different animals.
MEAT-EATING PLANTS
I want people to get passionate about plants," says Lisa Van Cleef about a new exhibit at the San Francisco Conservatory of Flowers. "Everybody gets excited about the zoo and animals, but once you start looking at plants you find they have a lot going on, too!"
Especially the carnivores, or meat eaters, that use the sneakiest of tricks to trap their insect dinners. Take bladderworts, for example. They appear so small and delicate growing in a quiet pond. But these are the fastest-known killers of the plant kingdom, able to suck in unsuspecting mosquito larvae in 1/50 of a second using a trap door!
Once the trap door closes on the victim, digestive enzymes similar to those in the human stomach slowly consume the insect. When dinner is over, the plant ejects the remains and is ready to trap again.

Carnivorous plants grow in places with soil that doesn't offer much food value. "You and I could take a vitamin pill," says Van Cleef. "But these amazing plants have had to evolve over thousands of years, developing insect traps to get their nutritional needs met. Just look at all they've done in the fight to survive."
The traps can be well-disguised to fool the eye, like pitcher plants, which get their name because they look like beautiful pitchers full of nectar.
The Asian pitcher plant, for example, has a brightly colored rim and an enticing half-closed lid. Curious insects are tempted to come close and take a sip, then slide down the slippery slope to their deaths.
Hair-like growths along the pitcher walls ensure that nothing can scramble out, and the digestive enzymes can get to work. A tiny insect called a midge might be digested in a few hours, but a fly takes a couple of days.
Some of these pitchers are large enough to hold two gallons (7.5 liters). Carnivorous plants only eat people in science fiction movies, but once in a while a small lizard, rodent, or bird will discover that a pitcher plant isn't a good place to get a drink.

Other plants have found different ways to grab a bite. Sundews and butterworts snag snacks with flypaper-like stickiness, while the Venus flytrap snaps shut on its victims.
Carnivorous plants grow mostly in wet areas, from sea level to the mountains. They may seem exotic, but if you live in the United States, you don't have to travel to faraway lands to see some. North America has more carnivorous plant genera than any other continent.
If you can't travel to the exhibit in San Francisco, check out a carnivorous plant guidebook from your local library, and you may discover some growing in your neck of the woods!

Lisa Van wants people to get passionate about
plants because everybody gets excited about the zoo and animals, but once you
start looking at plants you find they have a lot going on.
Especially the
carnivores, that obtains vitamins of insects. They seem so small and delicate
but they have developed insect traps over thousands of years. They are
beautiful and flashy, so insects try to drink their nectar and the plants kill
them. They can’t eat human (only in films) but some of them can eat birds and
animals like a mouse.
This new show us that
plants could be interesting like animals. There are different types and we
normally think that only exist the plants that we see in gardens. So we must to
learn more about them, and maybe we can enjoy doing that.
