About our website

Acid rain
Acid Rain

There are many forms of acid rain that are seen around the world. In parts of the world where there is wet weather, there is acid rain, acid snow, and acid fog. In parts of the world where there is dry weather, there is acid gas and acid dust. All of the lakes and streams in the world are normally slightly acidic. Heavy rainstorms or melting snow can cause the acidity in lakes and in streams to increase.

Acid rain is very harmful to the environment. Acid rain damages everything over a period of time because it makes the living things in the environment die.

An example of acid rain.

Global warming
Global warming

Global warming refers to the rising average temperature of Earth's atmosphere and oceans and its related effects. In the last 100 years, Earth's average surface temperature increased by about 0.8 °C (1.4 °F) with about two thirds of the increase occurring over just the last three decades. Warming of the climate system is unequivocal, and scientists are more than 90% certain most of it is caused by increasing concentrations of greenhouse gases produced by human activities such as deforestation and burning fossil fuel. These findings are recognized by the national science academies of all the major industrialized countries.

An example of Global Warming.


  • safeguarding the natural world 

  • tackling the global threat of climate change

    WWF is at the heart of global activities in all these areas. They have teams of highly skilled professionals working with governments, businesses and communities all around the world.


The underlying goal of all their work is a green and peaceful world - an earth that is ecologically healthy and able to nurture life in all its diversity.
