Deforestation

Rainforests - this is more than 50% of all green spaces of the planet. Over 80% of animal and bird species live in these forests. Today, deforestation of the rainforest is happening rapidly.

Forest exploitation

Scientists say that anthropogenic activity negatively affects the state of nature. Ecological problems of forests are one of the global problems of our time. If the forest is destroyed, then life will disappear from the planet. This needs to be realized by those people on whom the preservation of the forest depends. In ancient times, people revered the forest, considered it the breadwinner and treated it with care.

Forests of this type are found in Central and South America, in Africa and Asia, in Australia and on some islands of the Pacific Ocean. Climatic conditions As the name implies, tropical forests are located in a dry tropical climate zone.

Environmental soil problems

Over the past several millennia, human activity has done little damage to the environment, but after the technical revolutions the balance between man and nature has been disrupted, since since then natural resources have been intensively used. Soil has also been depleted as a result of agricultural activities.

Sahara Desert

One of the largest and most famous deserts on the planet is the Sahara, which occupies the territory of ten African countries. In ancient writings, the desert was called "great."

The most acute of the problems of the water area is a significant loss of water. Over fifty years, the area of ​​the reservoir decreased by more than 6 times as a result of uncontrolled land reclamation.
