Environmental conditions on Earth have changed with time. Increasing temperature, forest fires, and vanishing of water resources are indicators of the diminishing state of nature. Climate change is another picture that depicts a worsening state. Many activists have taken initiatives to educate the masses about the bad effects of their activities. On this day, World Humanitarian Day, here are highlights of how human activities have impacted nature. The effects of these activities are not only witnessed on flora and fauna but humans as well. 

According to a report by WHO, climate change is expected to cause approximately 250,000 additional deaths per year, from malnutrition, malaria, diarrhea and heat stress. The direct damage costs to health (i.e. excluding costs in health-determining sectors such as agriculture and water and sanitation) are estimated to be between $2- $4 billion per year by 2030.

Increase in Natural Disasters 

Earth’s atmosphere has deteriorated owing to bad human practices. Pollution, emission of Carbon Dioxide, and deforestation have harmed nature immensely causing an increase in the number of natural disasters. As per WHO’s report, the number of reported weather-related natural disasters has more than tripled since the 1960s. Rising sea levels and increasingly extreme weather events will destroy homes, medical facilities, and other essential services. Increasingly variable rainfall patterns are likely to affect the supply of freshwater. A lack of safe water can compromise hygiene and increase the risk of diarrhoeal disease. 

In 2019-20, a forest fire that occurred in Australia had burnt a large amount of land as well as animals. According to the CNN report, dozens of people died in Australia's 2019-2020 bushfire season, which was one of the worst on record. More than 10 million hectares of land burned and over a billion animals are estimated to have died, with many species pushed close to extinction. The Mint’s report shows that India recorded 3,45,989 forest-fire alerts between November 2020 and June 2021, the highest in the last three years and almost triple the number of alerts generated during the same period the previous year. The report states that Odisha recorded the highest number of forest-fire alerts at 51,968, followed by Madhya Pradesh (47,795) and Chhattisgarh (38,106) between November 2020 and June 2021.

Health Problems 

Besides the environment and animals, climate change is affecting the health of humans. A wide number of diseases infect human beings such as airborne diseases and water-borne ailments.  

The above-cited report informed that climate change is expected to cause approximately 250,000 additional deaths per year between 2030 and 2050; 38,000 due to heat exposure in elderly people, 48,000 due to diarrhea, 60,000 due to malaria, and 95,000 due to childhood undernutrition.

As per NCBI’s report, as a developing country with a high population density, India might experience myriad human health effects because of climate change. These effects could include infectious diseases such as malaria, chikungunya, and water-borne illnesses. 

The Rise in Earth’s Temperature 

A massive spike in high-air temperature led to deaths from respiratory and cardiovascular ailments, especially in elderly people. The above-stated report revealed that high temperatures increase ozone and other pollutants in the air, thus worsening cardiovascular and respiratory disease. These can trigger asthma, which affects around 300 million people.


These are some major effects of climate change that have been experienced. If ill human practices would be regulated, then the impacts of global warming can worsen in the offing.
