PRACTICE TEST 1 What will the speaker most likely discuss next?

[00:00.00][00:00.23]Listen to a talk in an environmental science class.
[00:01.00][00:06.01]Professor: An ecological footprint is a measure of the environmental impact of an individual, community, or country. [00:13.01]It calculates the amount of natural resources consumed and the waste generated by human activities, usually expressed in global hectares. [00:23.29]By comparing ecological footprints, we can understand how different lifestyles and practices contribute to resource depletion and environmental degradation. [00:33.14]For instance, the ecological footprint of someone living in a developed country is typically larger than that of someone living in a developing country, mainly due to higher consumption levels and waste production.
[00:02.00][00:45.68]Factors such as energy use, transportation, food consumption, and housing play significant roles in determining the size of an ecological footprint. Understanding ecological footprints is crucial for promoting sustainability. [01:01.52]It helps identify areas where changes can be made to reduce environmental impact. [01:07.83]For example, if you consume locally produced foods, you'll likely reduce your ecological footprint because less energy will be used for transporting that food. [01:19.01]Governments and organizations can use ecological footprint data to develop policies aimed at achieving sustainable development. [01:27.41]I'll discuss some examples of that next.
