Climate Change Mitigation:
Global warming is one of the major issues in primary environmental challenges. It occurs due to excessive emissions of CO2. According to the a dissertation research, it has increased by 50% since 1990. In recent years, it is again increasing at an alarming rate. Due to this, the survival of millions of people is at stake. Apart from this, it is increasing the temperature of the environment. The temperature rises due to greenhouse gases in the atmosphere. As a result, we will face severe challenges in the near future. The global community should ensure that global warming is less than 2 ºC as per the Paris Agreement.Pollution Problems:
Pollution problems are another primary environmental challenge. The World Health Organization keeps a close eye on global health. According to a report by WHO, 90% of the global population breathes polluted air. Polluted air is the major reason behind emphysema, asthma, and respiratory diseases. If the air pollution rate keeps rising, it will cause 7 million deaths in a year. Contaminated water is another key challenge and leads to 5 million deaths in a year. So, there is a strong need to stop polluting our environment. We should make sure to avoid dumping and use of harmful chemicals.Protecting the Oceans:
In our daily life, we waste a lot of fresh water. We can waste it in several different ways, such as using harmful chemicals. This wasted water is highly polluting the oceans. Apart from this, this water contains plastics too. So, oceans are becoming a great source of dumping plastic. It is very harmful to sea creatures and to the environment too. The UN is addressing this issue as a top priority. It is also urging the global community to adopt the management of protected areas. It will help to protect the oceans and sea creatures.Overpopulation:
It is one of the most important primary environmental challenges. The current global population estimate is 7.9 billion, and in 2030, it will reach almost 8.6 billion. The global community is failing to meet the basic needs of humans. There is increasing food, water, healthcare demands with the rising population. As a result of this, it is also causing inequality. The developing countries are facing this issue with severe magnitudes. In the future, both developed and developing countries will face this issue. The global community needs to adopt serious measures. Otherwise, it will be difficult to deal with this issue in 2030.Biodiversity Loss:
Biodiversity is another primary environmental challenge. It means the disappearance of biological diversity due to habitat loss. Several species have become extinct, and a lot is near to getting extinct. One of the major reasons behind biodiversity loss is environmental degradation. The global community is facing serious biodiversity loss, and it will face more in 2030. Cutting trees for agricultural and industrial purposes leads to habitat loss. The UN is addressing this issue with key consideration. It launched a Decade on Ecosystem Restoration (2021-30) to prevent this issue.Also Read This: Is New Curriculum Meeting the Demands of Future Workforce?
