Global environmental major issues:

One of the primary causes of environmental degradation in a country could be attributed to the rapid growth of population, which adversely affects the natural resources and environment.
The uprising population and environmental deterioration face the challenge of sustainable development.
The existence or the absence of favorable natural resources can facilitate or retard the process of socio-economic development.
The three basic demographic factors of births (natality), deaths (mortality) and human migration (migration) and immigration (population moving into a country produces higher population) produce changes in population size, composition, distribution, and these changes raise a number of important questions of cause and effect.
Population growth and economic development are contributing to many serious environmental calamities in India. These include heavy pressure on land, land degradation, forests, habitat destruction, and loss of biodiversity.
Changing consumption pattern has led to a rising demand for energy. The final outcomes of this are air pollution, global warming, climate change, water scarcity, and water pollution.
Environmental issues in India include various natural hazards, particularly cyclones and annual monsoon floods, population growth, increasing individual consumption, industrialization, infrastructural development, poor agricultural practices, and resource mal-distribution have led to the substantial human transformation of India’s natural environment.
An estimated 60% of cultivated land suffers from soil erosion, waterlogging, and salinity.
It is also estimated that between 4.7 and 12 billion tons of topsoil are lost annually from soil erosion.
From 1947 to 2002, average annual per capita water availability declined by almost 70% to 1,822 cubic meters, and overexploitation of groundwater is problematic in the states of Haryana, Punjab, and Uttar Pradesh.
Forest area covers 18.34% of India’s geographic area (637000 km²). Nearly half of the country’s forest cover is found in the state of Madhya Pradesh (20.7%) and the seven states of the northeast (25.7%); the latter is experiencing net forest loss.
Forest cover is declining because of harvesting for fuel wood and the expansion of agricultural land. These trends, combined with increasing industrial and motor vehicle pollution output, have led to atmospheric temperature increases, shifting precipitation patterns, and declining intervals of drought recurrence in many areas.
The Indian Agricultural Research Institute of Parvati has estimated that a 3°C rise in temperature will result in a 15 to 20% loss in annual wheat yields.

These are substantial problems for a nation with such a large population depending on the productivity of primary resources and whose economic growth relies heavily on industrial growth.

Environmental issues at the global level

Depletion of natural resources
Water pollution
Air pollution
Groundwater pollution
Toxic chemicals & soil pollution
Ozone layer depletion
Global warming
Loss of biodiversity
Extinction of wildlife and loss of natural habitat
Nuclear wastes and radiation issues

Hence, the Global environmental problem is mainly due to the increasing Population.

Which of the following is NOT seen as the role of a teacher in teaching through problem-solving?

View answer

Read the given passage and answer the following questions - (1) Wildlife conservation plays a vital role in sustaining the health and diversity of our planet's ecosystems. By protecting natural habitats, conservation efforts ensure the survival of many species that are threatened by habitat loss, pollution, or poaching. These measures include establishing protected areas, such as national parks and wildlife reserves, where ecosystems can function naturally without human interference.(2) In addition to habitat protection, wildlife conservation involves research and monitoring activities to understand the needs of different species and the threats they face. Through tagging, tracking, and population studies, scientists can gather crucial data that informs conservation strategies and helps mitigate the impacts of climate change and human activity on wildlife populations.(3) Community engagement is another essential aspect of effective wildlife conservation. By involving local communities in conservation efforts, awareness about the importance of biodiversity is increased, and sustainable practices are encouraged. This includes educational programs that teach the value of wildlife and ecosystems, as well as initiatives that promote coexistence between humans and wildlife. Together, these measures contribute not only to the protection of wildlife but also to the well-being of human populations, by maintaining the balance of ecosystems that provide us with essential services such as clean air, fresh water, and pollination of crops.What is a significant outcome of engaging local communities in wildlife conservation efforts?
