the ecological unbalance is caused by

• Various factors such as deforestation, pollution, climate change, overpopulation, and habitat destruction.
• Chocolate consumption
• Alien invasion
• Moon phases

what are the effects of deforestation on the environment?

• Increased carbon dioxide levels and loss of biodiversity

• Improved air quality and enhanced wildlife habitats

• Reduced soil erosion and promotion of ecosystem balance

• Higher levels of oxygen and decreased global temperatures

how does pollution impact marine life?

• It leads to water contamination and disrupts aquatic ecosystems

• It promotes the growth of marine species and enhances biodiversity

• It reduces ocean acidity and supports coral reef growth

• It has no significant effect on marine life

what role does overpopulation play in environmental degradation?

• It strains limited resources and accelerates habitat destruction

• It promotes sustainable living practices and conserves natural habitats

• It reduces pollution levels and supports wildlife conservation

• It has no impact on the environment

which of these is an effect of deforestation

• Prevention of soil erosion
• Loss of habitat for wildlife, disruption of ecosystems, increased greenhouse gas emissions, and soil erosion
• Decreased air pollution
• Promotion of biodiversity

How does industrial pollution contribute to environmental degradation?

• It contaminates air, water, and soil, leading to health hazards and ecosystem disruption

• It promotes sustainable practices and conserves natural resources

• It reduces pollution levels and supports wildlife conservation

• It has no impact on the environment

What are the consequences of greenhouse gas emissions on the planet?

• They trap heat in the atmosphere, leading to global warming and climate change

• They promote the growth of plants and enhance biodiversity

• They reduce pollution levels and support marine life

• They have no significant effect on the environment

How does habitat destruction impact wildlife?

• It leads to loss of natural habitats, displacement of species, and extinction risks

• It promotes the growth of wildlife populations and enhances biodiversity

• It reduces pollution levels and supports ecosystem balance

• It has no significant effect on wildlife
