Environment Impact of Food Production

### Context

As the world’s population has expanded and gotten richer, the demand for food, energy and water has seen a rapid increase. Not only has demand for all three increased, but they are also strongly interlinked: food production requires water and energy; traditional energy production demands water resources; agriculture provides a potential energy source. This article focuses on the environmental impacts of food. Ensuring everyone in the world has access to a nutritious diet in a sustainable way is one of the greatest challenges we face.

### Content

This dataset contains most 43 most common foods grown across the globe and 23 columns as their respective land, water usage and carbon footprints.

Columns
1. Land use change - Kg CO2 - equivalents per kg product
2. Animal Feed - Kg CO2 - equivalents per kg product
3. Farm - Kg CO2 - equivalents per kg product
4. Processing - Kg CO2 - equivalents per kg product
5. Transport - Kg CO2 - equivalents per kg product
6. Packaging - Kg CO2 - equivalents per kg product
7. Retail - Kg CO2 - equivalents per kg product

These represent greenhouse gas emissions per kg of food product(Kg CO2 - equivalents per kg product) across different stages in the lifecycle of food production.

Eutrophication – the pollution of water bodies and ecosystems with excess nutrients – is a major environmental problem. The runoff of nitrogen and other nutrients from agricultural production systems is a leading contributor.

随着全球人口的增长与财富的积累，对食物、能源和水资源的需求亦急剧上升。不仅三者需求增加，它们之间亦相互紧密关联：食物生产需依赖水资源与能源；传统的能源生产则需消耗水资源；而农业亦提供了一种潜在的能源来源。本文着重探讨食物对环境的影响。确保全球每个人都能以可持续的方式获得营养均衡的饮食，是我们面临的最大挑战之一。

本数据集涵盖了全球最常种植的43种食物，以及它们的土地、水资源消耗和碳足迹的23个相关列。

列名及内容如下：
1. 土地使用变化 - 每千克产品二氧化碳当量（Kg CO2 - equivalents per kg product）
2. 动物饲料 - 每千克产品二氧化碳当量（Kg CO2 - equivalents per kg product）
3. 农场 - 每千克产品二氧化碳当量（Kg CO2 - equivalents per kg product）
4. 加工 - 每千克产品二氧化碳当量（Kg CO2 - equivalents per kg product）
5. 运输 - 每千克产品二氧化碳当量（Kg CO2 - equivalents per kg product）
6. 包装 - 每千克产品二氧化碳当量（Kg CO2 - equivalents per kg product）
7. 零售 - 每千克产品二氧化碳当量（Kg CO2 - equivalents per kg product）

上述列代表了食物生产生命周期不同阶段的每千克食品产品的温室气体排放量。

富营养化——水体和生态系统因过量营养物质而受到污染——是重大的环境问题。农业生产系统中氮及其他营养物质的流失是导致这一问题的主因。
