Challenge Accepted!

Overview

Human activities impact our environment and cause many issues for our planet such as global warming, air pollution, and destroying wildlife. We are focused on human activities in order to influence environmental issues from down to top (From People to Government).

Problem

Environmental problems at local and global levels.

• Energy

  According to recent stats, with “a 60% rise in CO2 emissions over the last 30 years,” the urgent need for sustainable, efficient energy solutions is clear.

• Sport

  1 in 5 adults around the world exercise or play sports regularly, with 5.3% participating daily. This statistic is a powerful reminder of the importance of physical activity in our lives.

• Food

  The volume of global food consumption has been ever-increasing since 2015. In 2021, the global consumption of food reached 2.5 billion metric tonnes.

• Reuse

  According to the European Circular Economy Stakeholder Platform, every year Europeans consume, on average, more than 16 kg of clothing per person, but less than 40% of used clothes are collected for reuse or recycling.

• Environment

  In 2021, the municipal waste per inhabitant in Germany amounted to a total of 646 kilograms. This was significantly above the EU average of 530 kilograms.

• Transportation

  The car is the dominant mode of transport in the EU, with less than 2 persons on average per car. The EU-wide carbon dioxide emissions from road transport have increased by 21% since 1990. Passenger cars account for more than half of the annual emissions.
