1. Biodiversity loss means the disappearance of species and the reduction in the variety of life forms in an ecosystem. It occurs when habitats are destroyed, pollution increases, or invasive species spread. This loss weakens natural systems, reduces resilience to change and affects essential servicesRead more

    Biodiversity loss means the disappearance of species and the reduction in the variety of life forms in an ecosystem. It occurs when habitats are destroyed, pollution increases, or invasive species spread. This loss weakens natural systems, reduces resilience to change and affects essential services like pollination or clean water. Protecting biodiversity ensures food security, stable climates and ecosystem balance. Conservation efforts are key to reversing this trend.

    Renewable resources are naturally replenished and include solar energy, wind, water and forests. They differ from non-renewables like coal or oil, which take millions of years to form. People must use renewable resources wisely to avoid overuse. Conservation, replanting trees, using solar panels and reducing water waste help maintain them. Sustainable use ensures these resources are available for future generations too.
