Explore essential facts about sustainability, the challenges of climate change, and how green technology plays a role in building a better future for our planet.
Which statement best describes the concept of sustainability?
Explanation: The correct answer highlights that sustainability balances current resource use with future needs. Maximizing growth regardless of environmental impact ignores long-term consequences. Rapid resource use undermines future availability. Focusing solely on technology overlooks environmental and social aspects crucial to sustainability.
What is the main human activity contributing to the increase of greenhouse gases in the atmosphere?
Explanation: Burning fossil fuels like coal, oil, and natural gas emits significant greenhouse gases, primarily carbon dioxide. Planting trees and reducing energy use help lower emissions, while renewable energy replaces fossil fuels, all aiding in mitigation rather than causing the issue.
Which is a direct effect of climate change on Earth's systems?
Explanation: Climate change directly leads to higher temperatures, causing polar ice caps to melt. Technology advancements and new mineral finds are unrelated or only indirectly linked. Increased agricultural yields are not guaranteed; climate change can actually disrupt food production.
What is a key goal of adopting sustainable practices in industries like agriculture and transport?
Explanation: Sustainable practices aim to lower greenhouse gas emissions through efficient resource use and renewable energy. Using more plastics, extracting fossil fuels, or limiting regulations generally work against sustainability and often increase emissions.
What is the primary aim of international agreements like the Paris Accord?
Explanation: Agreements such as the Paris Accord focus on limiting how much global temperatures increase to prevent severe climate impacts. Increasing fossil fuel trade, reducing renewables, or lowering food standards are not objectives and may actually worsen climate change.
