FAQs on How do we contribute to environment problems - Our Environment, Science, Class 10 Video Lecture

1. How do human activities contribute to environmental problems?
Ans. Human activities contribute to environmental problems in various ways. Some of the main ways include deforestation, industrial pollution, emission of greenhouse gases, improper waste disposal, and excessive use of natural resources. These activities can lead to habitat destruction, air and water pollution, climate change, and loss of biodiversity.
2. What are the effects of deforestation on the environment?
Ans. Deforestation has several negative effects on the environment. It leads to the loss of habitats for many species, disrupts the balance of ecosystems, increases soil erosion, and reduces the absorption of carbon dioxide from the atmosphere. Deforestation also contributes to climate change as trees play a crucial role in regulating the climate by absorbing carbon dioxide and releasing oxygen.
3. How does industrial pollution impact the environment?
Ans. Industrial pollution has severe impacts on the environment. The emissions from industries release harmful pollutants, such as sulfur dioxide, nitrogen oxides, and particulate matter, which contribute to air pollution. These pollutants can cause respiratory problems, cardiovascular diseases, and even cancer in humans. Industrial pollution also contaminates water bodies, leading to water pollution and the death of aquatic organisms.
4. What are the consequences of improper waste disposal?
Ans. Improper waste disposal can have significant consequences for the environment. When waste is not disposed of correctly, it can contaminate soil, water sources, and air. This contamination can lead to the spread of diseases, damage to ecosystems, and harm to wildlife. Improper waste disposal also contributes to the emission of greenhouse gases, contributing to climate change.
5. How does excessive use of natural resources affect the environment?
Ans. Excessive use of natural resources puts a strain on the environment. When resources like fossil fuels, minerals, or water are overexploited, it can lead to their depletion and scarcity. This can disrupt ecosystems, impact biodiversity, and further contribute to climate change. Additionally, the extraction and processing of natural resources often involve environmental degradation and pollution, causing long-term damage to the environment.
