Our Precious Environment

Deer, bears, salmons, pelicans, elephants, oaks, desert plants, algae, lichens – any list representing the gigantic variety of species on the Earth is unavoidably an unending one. Numerous creatures and plants occupy our greenery enclosures; others live on high mountains or in vivid sparkling coral reefs. Every one of them have adjusted to their condition with a specific end goal to survive. This is more valid on account of creatures that live in deserts or in greatly cool areas. Unfortunately, we are increasingly destroying the natural surroundings of creatures. From one perspective, we are clearing woods and contaminating oceans and waterfront regions. Then again, we are endeavoring to secure the earth by recycling waste, building national parks and unwildlife sanctuaries, and propelling reproducing programs in zoos.

What do plants live on?

We know very well what animals eat. But what do plants do to live? Do they survive only on water and light? How do they survive only on water and light? How do they reproduce? How are the annual rings on the trunks of trees formed? Why do leafy plants shed their leaves in autumn, while coniferous plants retain their needles? These questions and many more are discussed here.

Why are so many animal species endangered?

Over many hundreds of years, scientists have discovered approximately 1.5 million species – many are now extinct and many others have not yet been discovered! About 150 years ago, a British researcher found out what caused emergence of species. Since then, we have come to know a lot regarding te reasons behind the gradual extinction of various species.

Life forms in natural habitats

Gardens natural habitats forests, mountains, and coastal areas are all natual habitats, which are homes to various kinds of living things. Do we really know them? Do we know why mixed forests are healthier than coniferous forests, why marmots whistle, or what ‘salt meadows’ are? Usually we are more interested in studying distant and exotic places like the Himalayas or the Andes!

Life in the forests and tropical seas

In the tropics, where the sun is warm and bright, nature offers a broad spectrum of colour. Animals use bright colours to attract partners and gaudy ones to drive away predatory creatures. Every natural habitat is an exciting world. Small animals, such as corals build huge reefs, and giant trees use various techniques to cling on to the soil, which is often only a few centimetres deep.

Life in the savannas, deserts, and the Polar Regions 

What do the savannas, deserts and the Polar Regions have in common? Life in them is extremely difficult. During summer, the savannas are green and have ample nutrition for all life forms, but in the dry period survival becomes difficult. In deserts, cacti use special techniques to live and grow, and the Polar Regions are inhabited by animals who have successfully adapted to an extremely cold and harsh environment.

What can we do to save the Environment?

Since ages, man has dumped garbage in the seas, fired crude oil, and caused water and soil pollution. Large forested areas have been cleared for farming or for wood. The worst part is that we carry on with these irresponsible acts. At the same time we also try to protect the environment by building national parks and zoos, or by finding new eco-friendly ways to produce energy and food stuffs.
