Interaction between the natural environment and human activities with reference to tropical rainforests

The growth in human population is always a problem for the environment because as the population grows the human habitation requires more space for agriculture, energy and development space. Rain-forest covers a huge area of the world’s tree surface and human beings have encroached to the rain-forest areas and many trees are cut for their convenience. More than 90,000 square miles of forest are harvested for the use of human beings. Deforestation increases the speed of global warming and changes the climate of the rain-forest. Because of the change in climate in the rainforests, many species of plants and animals are lost all over the world. Because of the change is climate more than 2% of the rain-forest is lost annually.

Major Impact on Tropical Forest

The agriculture, mining and lumber industries create the major impact on the tropical rain-forest. All these types of industries require a lot of areas of the forest to run the industry. Mining takes the major chunk of the rain forests to build road to have access to the mines. These industries also affect the diversity in the tropical rainforests because of the loud construction noise and the pollution they create. The soil fertility of the area cleared is good only for growing crops only for a few years and the farmers clear more of the forest to satisfy their customers. The temperature of the tropical rainforest is generally high and the annual temperature range from 30 degrees Celsius in inland and 10 degrees Celsius on the coast. Moreover the sun is always high in the sky in the rain-forest regions.

The effect of the climatic changes on tropical forests is a global and regional concern and this is due to the high biodiversity and the possible reaction to carbon, nutrient and water cycles. The major aspects of changing climate can be viewed by the large scale consequences of the climate and even the change in the vegetation. The main reasons of biodiversity decline are land use changes, changes in atmospheric CO2 concentrations, pollution, difference in nitrogen cycle, acid rain, climate variations and the introduction of exotic species and all these are connected to human population growth. Land conversion is the primary factor which affects rainforests.

Less Change in Tropical Regions
The climate in tropical regions hardly changes because nitrogen is not so important and the growth in rainforests is limited more by low phosphorus levels than because of nitrogen deficiency. The major cause of the loss of biodiversity is because mainly because of the rise in human population all over the world. Population overtakes all the other problems created to the rainforests.

Human beings earlier go in for undisturbed areas whether it is suitable for cultivation or not and convert these into cultivable lands. But nowadays people are going in for land with high biodiversity because of the rich soil and other attractions. This is major threat for biodiversity and is also a threat to the commonly seen endangered species in the area. Habitat destruction is the most important cause of the loss of rain-forest biodiversity and this is directly related to human population growth.
