How can we save the environment
Welcome to the Earth's Kids Environmental Activism page! This is the place to learn more about our environment and it's various habitats. This is also where you can learn how to take action to make the world a better place for all the creatures we share this Earth with!
When the first astronauts traveled out into space they were struck by an amazing vision: planet Earth, sitting like a blue and green jewel in the blackness of space. An extraordinary place of life, and the only planet we know of that definitely has life, and in such abundance.
And the more scientists learn about life on Earth, the more they realize that Earth is wrapped in a delicate web of environmental systems that connect, each to the other. Food webs, climate cycles, ocean currents, animal migrations, carbon/oxygen exchange and so on.
We are now aware that changes in any one of these systems can have a huge impact.
Similarly, other changes underway, such as human beings cutting down forests to harvest wood and clear new farmland destroys wild animal habitats, and in many cases the animals themselves. It even drives many native peoples from the land. It often creates top soil erosion and destroys the forest watershed that provides clean drinking water to cities downstream. And it slows the exchange of carbon dioxide into oxygen. Which in turn causes global temperatures to rise.
Too much carbon dioxide leads to temperature changes. which leads to krill die offs in the ocean. which leads to the decline of fish populations that feed on krill. which leads to the ocean birds and mammals (penguins, whales, seals, etc.) that feed on fish struggling for food -- competing even more with human beings who are also finding the supply of fish dropping to dangerous lows. So low that not enough baby fish will be born and grow to maturity to supply the creatures that depend on them.
Scientists worry too that if all these systems get too off balance, nature may not be able to set things right again -- ever. Hopefully
that wouldn't be the case. Certainly planet Earth has been through some pretty major changes over the millenniums and although many species of creatures have become extinct, life on Earth has continued on, in some form or another. And new species always develop and multiply. So far at least. But as scientists look to some of the other worlds in our solar system, including moons of some of the larger planets, they wonder: did life thrive there once upon a time. until some terrible change or error happened that threw the delicate balance too far off? Could this happen to our own planet? Could we make this happen through careless harm to nature?
Even if changes that catastrophic could not happen-- that is, even if we could trust Earth to always find her balance again -- we know now that big enough changes are underway on our planet right now that we humans have to change our ways of doing things. if we don't want to be one of those species that goes extinct. Or, at the very least, if we want to cope effectively with the changes in weather patterns, crop growth, rainfall, pollution levels, global warming, and the depletion of our fisheries. So that we have enough food and water, clean air to breathe, and safe places to live.
But if it all seems overwhelming, consider this: right now we have more technological know how than we have ever had before. And we have more ability for scientists, inventors, activists, and world leaders to communicate with one another, all over the world, than ever before. We are able to spread the word about problems, share ideas, work together, pressure our leaders for change more effectively than any other generation in history.
Yes, the problem is big. But the group we have assembled to work on it is big too. And guess what? YOU are part of that group. You, your friends and family, even your teachers and kids at school. So do your part. Learn. Spread the word. Email your government leaders. Share your ideas and your concerns. Together we can make it happen. One step at a time.Source: www.earthskids.com
