The nature and the ecological problem

I want to begin my conversation with you about the ecological problems. As we know, the Earth is our home. The nature is depends on how we treat it, just as the house we live in depends on how we take care of it.

There are a lot of ecological problems in our world. People make these problems themselves, for example, dirty air from the factories chimneys makes it hard for us to breathe and it can cause illness and even death; the dirty water from factories can kill fish. People have cut a plenty of trees in the forests. But to save our planet and to improve our life we should clean the water, plant more trees, reduce pollutions of air. By the way, if we smoke less, we will save both our life and the life of the nature.

To be healthy we must breathe by the clean air, drink clean water and eat the food without chemicals.

Of course, I can talk a lot of time about this topic. But in conclusion I want to say that for a long time people have used their Earth home without thinking of what was happening to it. Now we see that we must treat it better!

The nature and the ecological problems .
Our planet is home to millions of different kinds of plant and animal species, which are linked in different ways. Together, they make up the complex world of nature. Unfortunately, co-habiting with humans brings up ecological problems. The most acute are pollution, acid rain, wildlife destruction, shortage of natural resources and global warming. These problems are interrelated as everything in the natural world depends on one another.

Wild plants and animals live in a particular set of surroundings, called their habitat. Nowadays people change habitats to suit their own needs - to create farmlands or build cities, for example. They also destroy wildlife habitats while mining or by building roads.

A lot of species - fish, reptiles, insects, birds, mammals - are disappearing fast. It’s reported that by 2030 25% of all animals, birds and insects may be extinct.

All living organisms breathe in oxygen, and breathe out carbon dioxide. We produce carbon dioxide when we burn things. Trees take this gas from the air, and produce oxygen. But in the last few years, people have cut and burnt large amount of rainforest.

Many plants in the world are known to be in danger or threatened with extinction. The world has over nine million square km. of forests. Paper and cardboard are made from wood. Every year over 100000 sq. km. of forests are cleared for different uses, and a lot of forests are so badly damaged that they will hardly be able to recover.

Acid rain falls when poisonous gases from power stations and vehicles mix with oxygen and moisture in the air. Acid rain poisons or kills wildlife in lakes, rivers, and forests, and damages the surrounding plant life. The problem could be controlled by reducing vehicle emissions and limiting the gases released from power stations.

World temperatures are currently rising every year. This phenomenon is called global warming. As the planet warms up, the water in the oceans will take up more space and water from glaciers and the polar ice caps will start to melt. This could cause sea levels to rise and many habitats will disappear under water.

The cause of global warming is attributed to the greenhouse effect. It works in the following way - sunlight gives us heat which warms the atmosphere. Some of the heat returns into space. Nowadays the air surrounding the earth has become much warmer because the heat can't go back into space. That's why winter and summer temperatures in many places have become higher.

Summing everything up, the climate in different parts of the world changes every year. These changes can be dangerous for our planet which needs protection. The measures to be taken include limitations for cutting rainforests and poisonous gas emissions as well as personal ecology of humans.
