Global ecological crisis : Over utilisation of resources has led to the global ecological crisis such as global warming, depletion of ozone layer, pollution and land degradation.

Two Global Ecological Crisis

There are many ecological crises faced by the world today, but two of the most pressing are climate change and biodiversity loss.

Climate Change

Climate change is the long-term alteration of temperature and typical weather patterns in a place. This can include changes in the timing and occurrence of seasons, precipitation, and temperature. The main cause of climate change is the increase in greenhouse gases, such as carbon dioxide, in the atmosphere due to human activities like burning fossil fuels.

Climate change has significant impacts on the environment, such as rising sea levels, increased frequency and severity of natural disasters, and changes in ecosystems. It also has social and economic impacts, such as displacement of people, loss of livelihoods, and increased healthcare costs.

Biodiversity Loss

Biodiversity loss is the decline in the variety of living species on Earth. This can occur due to habitat destruction, pollution, climate change, overexploitation of species, and introduction of non-native species. The loss of biodiversity has significant impacts on the environment, including loss of ecosystem services like pollination and nutrient cycling, and reduced resilience to environmental stressors.

Biodiversity loss also has significant social and economic impacts, such as loss of medicinal resources, reduced food security, and decreased tourism revenue.

Both climate change and biodiversity loss are complex and interconnected issues that require global action to address. This includes reducing greenhouse gas emissions, protecting and restoring habitats, and promoting sustainable land and resource management practices.
