familiar:adj.熟悉的;常见的;亲近的;n.常客;密友; algae:n.[植]藻类;[植]海藻;
Okay, so most of you are. 很好,大部分人都了解
I think we can all agree it's a serious issue . 我想大家都同意这是个严重的问题

Nobody wants to drink blue algae-contaminated water, or swim in a blue algae-infested lake. 没有人想喝被蓝藻污染的水 或者在被蓝藻污染的湖里游泳
Right? 对吧？
I hope you won't be disappointed, but today, I won't be talking about blue algae. 我希望大家不会失望, 虽然今天我不会讨论蓝藻。
Instead, I'll be talking about the main cause at the root of this issue, which I will be referring to as the phosphorus crisis . 但是我要谈论这个问题的根源 但是我要谈论这个问题的根源 我称它为“磷危机”
referring:v.引用;提到;将…归因于…;把…提交;(refer的现在分词) phosphorus:n.磷; crisis:n.危机;危险期;决定性时刻;adj.危机的;用于处理危机的;
Why have I chosen to talk to you about the phosphorus crisis today? 为什么今天我选择谈论磷危机？
For the simple reason that nobody else is talking about it. 很简单,因为没有人谈论它
And by the end of my presentation , I hope that the general public will be more aware of this crisis and this issue. 等我演讲完了,我希望 大众会对这个危机有更多的觉悟
presentation:n.展示;描述,陈述;介绍;赠送; general public:n.普通百姓;大众;公众;
Now, the problem is that if I ask, why do we find ourselves in this situation with blue algae? 现在,如果我问大家 为什么我们会有蓝藻问题？
The answer is that it comes from how we farm. 回答是这跟我们如何耕种土地有关
We use fertilizers in our farming, chemical fertilizers. 我们在耕种的过程中使用肥料,化学肥料
fertilizers:n.[肥料]肥料(fertilizer的复数形式);化肥;底肥; chemical:n.化学制品,化学药品;adj.化学的;

So, what does a plant need in order to grow? 那么,一株植物需要什么才能生长？
A plant, quite simply, needs light, it needs CO2, but even more importantly, it needs nutrients , which it draws from the soil. 一株植物,很简单,需要光和二氧化碳 但是更重要的是,它需要养料 它们从土壤中吸取这些养料
nutrients:营养盐;[食品]营养素;
Several of these nutrients are essential chemical elements : phosphorus, nitrogen and calcium . 有一些养料是非常重要的化学元素: 比如磷,氮和钙

Today I'll be focusing on a major problem that is linked to phosphorus. 今天我将重点谈一个和磷元素相关的重要问题
Why phosphorus in particular ? 为什么是磷？
in particular:尤其,特别;
Because it is the most problematic chemical element. 因为这是最有问题的一个化学元素
problematic:adj.问题的;有疑问的;不确定的;
By the end of my presentation, you will have seen what these problems are, and where we are today. 在我演讲之后,大家将会了解 这些问题是什么,以及我们面临的现状如何
Phosphorus is a chemical element that is essential to life. This is a very important point. 磷是生命必需的化学元素 这点非常重要
I’d like everyone to understand precisely what the phosphorus issue is. 我想让大家都准确地理解,磷问题到底是怎么一回事

Now, where do we find this phosphorus? 那么,我们在哪里找到这些磷呢？
As humans, where do we find it? 作为人类,我们在哪里找到它？
As I explained earlier, plants extract phosphorus from the soil, through water. 我之前已经解释过了, 植物从土壤里通过水来吸收磷
So, we humans get it from the things we eat: plants, vegetables, fruits, and also from eggs, meat and milk. 所以,我们人类通过食物来获取它: 植物、蔬菜、水果 还有蛋类、肉和牛奶
It’s true that some humans eat better than others. 那些“吃得比别人更好的人“
Some are happier than others. 确实”比别人过得更开心”

And the question is a simple one: Do we have enough phosphorus to feed our future generations? 问题很简单:我们有足够的磷 来养活这么多人吗？
So, in order to understand these issues , where do we find our phosphorus? 那么,为了理解这些问题, （我们要问）我们从哪里找到磷呢？
issues:n.重要议题;争论的问题;v.宣布;公布;发出;(issue的第三人称单数和复数)

Only 15 percent of this 100 percent goes to the plant. Eighty-five percent is lost. 这其中只有15％被植物利用。85％都浪费了
It goes into the soil, ending its journey in the lakes, resulting in lakes with extra phosphorus, which leads to the blue algae problem. 这部分进入到土壤,最终到达湖泊 最终导致湖泊里的磷过剩,导致了蓝藻问题

So, you’ll see there’s a problem here, something that is illogical . 那么,大家会发现一个不合逻辑的问题
illogical:adj.不合逻辑的;不合常理的;
A hundred percent of the phosphorus is used, but only 15 percent goes to the plant. 100％的磷被使用了,但最终只有15％被植物吸收

This is to show you that this method works. 这就证明这个方法是可行的
And in some cases, in Cuba, Mexico and India, the dose can be reduced to 25 percent, and in several other cases, there's no need to add any phosphorus at all, because the mushrooms are so well adapted to finding phosphorus and drawing it from the soil. 在某些情况下,在古巴、墨西哥和印度 磷肥的投入可以降到25％,在几个其他的例子里 根本不用添加任何的磷 因为这些菌类适应得非常好 可以完全从土壤中找到并吸收磷
