Deforestation promotes global warming


KARACHI: Human health and well-being are closely associated with forests which cover almost a third of the Earth’s land area and are essential to our environment in many ways. Forests maintain the hydrological cycle, conserve soils, prevent climate change, fix the concentration of carbon in the atmosphere and preserve the biodiversity of the land. In addition, many countries benefit from it for the production of wood and certain medicines.

Deforestation is the conversion of forests to permanent non-forested land for agricultural or urban development purposes. Tropical rainforests are also at the heart of the problem. The reduction in the area of ​​tropical forests leads to a loss of biodiversity and an accumulation of greenhouse gases in the atmosphere. Today the whole world is facing environmental problems due to massive deforestation. Uncontrolled deforestation has continued for a long time. As forests, including tropical rainforests, are destroyed, efforts are also constantly being made to conserve forests.

You have to understand why the forests are destroyed. Almost half of the clearing of tropical rainforests is intended for agricultural colonization. The expansion of agriculture continues to be the main driver of deforestation. As the world population increases day by day, it is necessary to provide them with food. Logging to harvest timber for multiple purposes also seriously degrades forests. Forest clearing is also underway to establish infrastructure for the expansion of towns and villages.

Deforestation has a devastating impact on the climate and biodiversity. It has also dramatically altered landscapes around the world. Forests are considered the main terrestrial carbon sink. Tropical rainforests are often referred to as the “lungs of the planet” because they attract carbon dioxide and exhale oxygen.

For example, the Amazon rainforest is the largest tropical rainforest in the world and provides 20% of the earth’s oxygen. Deforestation disrupts the global carbon cycle. Unbridled deforestation increases the concentration of carbon dioxide in the atmosphere, leading to global warming as the carbon dioxide traps thermal radiation. Global warming is the main cause of flooding and melting of polar ice caps.

Deforestation also disrupts hydrological cycles and climatic regimes. It also results in hotter and drier weather, increasing droughts and desertification. Deforestation also contributes to the loss of vegetation due to soil erosion. Biodiversity, the diversity of life on Earth, is essential for the proper functioning of ecosystems. Forests are home to most of the Earth’s terrestrial biodiversity. Forest biological diversity encompasses not only trees, but the multitude of plants, animals and microorganisms that inhabit forest areas. Deforestation and forest degradation continue to take place at alarming rates, resulting in loss of biodiversity due to habitat loss. Scientists predict that many species will suffer and eventually become extinct due to habitat loss.

This highlights the critical need to conserve forests in order to conserve biodiversity. The planet has already lost at least half of the forests, and the rest are indeed being eliminated. There must be regulated and planned tree cutting, afforestation programs must be initiated, and there must be appropriate controls over the clearing of forests for agricultural establishment or urban development.

Actions to combat deforestation and illegal logging must be taken to protect forests is associated with environmental health.

The new challenges of climate change require urgent action to explore and protect the local value of forests. All necessary steps must be taken to fix the problem before it invades us.
